Are you satisfied with your phone's battery backup??? If not,follow the tutorial,you will surely have a better battery life.
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. An app called battery stats caliberator does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully
discharge after calibration, then charged to 100% without break.
The app shows your actual battery status, and only allows
you to start the calibration (i.e. removes the file) when
it's fully charged, unless you force earlier calibration. The voltage meter can be useful too. Full charge is around
4200mV.
There is an option to beep when 100% is reached so you
don't have to closley follow the changes.
Get this app and deatils ==>> http://www.techmaafias.com/2014/05/how-to-clear-battery-stats-for-better.html

Proper way to callibrate battery??lil bit explaination
wipe cache and battery stats -> download a ,,battery calibration'' from market and then follow instructions in the app.

Would u tell when to unplug charger after which step
And should to remove battery stats from recoveryas well as through that app????
Charge your phone to 100%, reboot into recovery remove your charger than wipe battery-stat. Reboot. Use your phone as regular use and let it die (completely to 0%) of battery with no charging in between. After that charge your phone to 100% at a stretch without any break like at night from 0% to 100% without break.

Calibration of Li-Ion batteries is nonsense. You can do any ritual and accompany it by a pole dance when the moon is full and it will have about the same effect like these "calibrations" and snake oil utilities that claim to perform such things.
These batteries degrade by heat. If you still insist, simply let it discharge until the phone turns off, charge to 100%, wipe the stats, repeat once more. Done. No utilities needed.

Battery Drain
I've been thinking about this the other day that the battery calibration app & wiping battery stats in recovery were just the same.
I just had the weirdest battery drain after I uninstalled the battery calibration app last night. I had around 80% battery before I slept & had almost 9 hours of sleep. When I woke up, I only had 35% battery??!! I'm using Devoid Franco plus his kernel & the phone was just idle as far as I know.
My fully charged battery lasted for a day & a half prior to this shocking battery drain.
Has anyone had a similar experience?
Hi,
The battery voltage (located in: CM7 spare parts >battery information) on my galaxy sii is reading between 3646 and 3648. First, I'm not sure if that is low, or if it is necessarily good or bad. I just can't seem to find an answer for this anywhere on the Internet, so I made started this thread.
Second, I was wondering what everyone else's battery voltage reading was on their galaxy s2.
Oh, and I also just did a battery calibration. ... If you didn't watch the video, Then I'll fill you in. I wiped my battery stats through recovery mode, then I let my phone drain its battery. BUT, in the process, my phone crashed (the screen froze) at around 1-5%. So I left it overnight and it eventually died. Then I plugged it in and left it till it fully charged to 100%. SO i was wondering if that could have messed up my battery voltage (the crash)?
Sorry if this was hard to understand... But I hope someone out there can help me with battery voltages! ><

Never drain battery to zero. Read plenty of users with different phones and ROM having issues in the past after draining to zero.
Should be approx 4200mV at 100% (approx 3500mV at zero).
1. I just drain to 1-2% (>3510mV) to be safe.
2. Charge uninterrupted to 100% and mA stops actual charging at approx 4200mV. As you will see, battery continues to charge for a time (mV increases) after 100% is reached.
3. Immediately delete battery stats. I use app Battery Monitor Widget to monitor current mA & delete without restarting, give SU permission (phone uses power to boot into CWM, and therefore not accurate at time of delete with this method).
4. Immediately unplug.
Done.

Hello,
I have ordered a new higher MAH battery for SGS II . I may be running stock ROM/Kernel or any of the custom AOSP ROM/Kernel.
During the kernel/ROM updates I have read that we dont usually need to clear the battery stats (since we are using the same existing battery).
However I will now be using the following battery :
http://www.amazon.com/gp/product/B0058SJ5Q4/ref=oh_o00_s01_i02_details
I need to how to properly calibrate the battery status so I can achieve full charge and maximum run time from this battery. Do I need to clear battery stats (from recovery mode) first and then insert the battery for first time usage or otherwise.
Have read a couple of posts on the subject however none provides a clear defined and fixed approach to the issue.
Any detailed guidance would be appreciated to be of benefit for the community in general.
Thanks.
=================================
Guess there are already enough methods and ways and some even debunk the myth that does the phone really needs any type of calibration/calibration apps at all or not.
Will try diving into it directly to see the effects myself if any.
You don't need to do anything other than sticking it in your phone.
When I got the 2000mah battery, I found my battery life to be equal or even slightly less than the stock one. I fully charged the battery, went to cwm and wiped battery stats, used battery completely till it died and then fully charged once again. It did seem to work as my battery life was much better.

He's right. Your battery calibrates itself with a full charging.
i read in a number of articles that you should reset/wipe your battery stats with CWM once your battery is at 100%, then switch off your phone and connect to a charger usb/plug until it will be charged to the actual 100% (usually only 1-2% at most)...

All 100% wrong .
As it only wipes the stats that show and plays no part in calibration of the battery .

thnx for the correction, what do you think about "Battery Monitor Widget" app? Does its function to calibrate actually work?
Got intrigued by the issue...
No, it doesn't. Due to hardware 'limitations', battery apps can only provide a rough guess at best of charge remaining, discharge rate, etc on SGS2.
And genuine (made by Samsung) batteries don't have to be (and cannot be) calibrated. There's a fuel gauge chip in the battery which does this automatically.
Some people having issues with the battery report charging to 100%, removing the battery for a few minutes (so the fuel gauge chip doesn't have power for that time) & putting it back in the phone fixes their issues, but even that sounds like voodoo to me.

Hello guys. After calibrating my battery and wiping my battery stats my battery mV value is 4327 mV. Is it ok or should i recalibrate it?
I think battery calibration is just a myth. I doesn't do anything at all.
Of course it works....how do you think your phone knows how much battery life you have?? Theirs a batterystats script somewhere in the firmware, and by editing that (wiping battery stats) your phone believes your battery is fit as a fiddle, the next thing to do after wiping battery stats is to maintain battery efficiency by 1. Not charging every day 2. Running your battery down completely (once a month or maybe twice) and 3. Not having LWP and unecessary apps running I.e task killers, anti virus. Turn your brightness down, data off when your connected to wifi (and vice versa), bluetooth off when your not using it. Just little things help massively once you get into the routine of maintaining your battery, it becomes easier, I get at least a day and a half out of mine with moderate/heavy usage

of course in most cases I will not do this trick but for battery recalibration since my phone battery indicator is totally a joke
I wanna give it a shot just once but I am worried because somebody says it will harm the battery life or even worse, let it dead(neither turned on nor charged). and many people also swear by completely discharging the battery all the way down and recharge it to 100% from time to time to reset the battery stat and have it work as it used to
so these two claims are contradictory each other so one of them is wrong.
please point out the right way for me. thanks
it likely won't kill the battery if it happens once (or occasionally), but i don't think it is recommended to do this regularly.
battery indicators are never perfect.
First of all, completely draining your battery could damage your phone and would reduce your battery lifespan. I recommend you to stop using the phone when the battery drops to 5-15%.
And battery calibration is 100% myth. Battery calibration just removes batterystats.bin and re-generate a new one. Android does the same once our device is fully charged.

well you're true but not all about the battery calibration,there another method which work and not a myth.the method is by charging upto the devices's limit voltage it can hold,you may have seen about "please charge your device 10 minutes more" its actually calibrating the phone's battery.but dont too overcharge it,it may get damaged,so be careful.

You mean trickle charging? It's for stabilize battery's voltage.
